Preparation and Characterization of Porous Materials from Pineapple Peel at Elevated Pyrolysis Temperatures.

[ 19 ] prepared PP-based biochar products at three temperatures (350, 500, and 650 °C) with a heating rate of 10 °C/min for 3 h, and they showed an increasing trend for its pore properties based on the Brunauer–Emmett–Teller (BET) surface area (i.e., it increased from 0.82 to 6.64 m 2 /g).

However, the adsorption rate constant k and the initial adsorption rate h showed a decreasing trend at larger initial MB concentrations because of the limited available adsorption sites.
